menses,

To (172 whom it may concern: I

Be it known that I, EDWIN RUUD, a citizen of the United States, and resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful improvements in Incinerators of Which the following is a"specification.

The primary object oifvthe invention is to provide a sample and eliicient garbage and other refuse incinerator designed primarily for'household use, with the various parts thereof readily accessible and of such construction that they may be conveniently assembled and disassembled. further'purpose is to provide a furnace structure wherein machine work is avoided by forming the same )rimaril of castilws that leave the l a foundry in condition to be assembled.

.The invention includes a novel construction and arrangement of a grate and grate support, sectional fire pot, and gas burner, with improved means for removably supporting the same in the furnace body. The construction is also such as to facilitate the insertion and removal of the burner and fire pot through a lateral door of the body provided for the purpose, the pot being formed in sections that may be readily entered and withdrawn through the door, and thelatter being also of sullicient size to pass the" burner which is preferably of ring-like one-piece construction.

The invention also embodies a sectional liner of novel construction which may be removed from the outer jacket or casling upon removing the detachable casing top or crown. The invention also contemplates a grate of improved construction, together with novel means "for rockingthe same.

In the accompanying drawings, Figure 1 is a perspectiveView of the improved incinerator. Fig. 2 is a vertical longitudinal sectional view taken centrally through the several doors with which the structure is provided. Figs. 3 and et are sectional plan Views taken on lines 3-3 and el4, respectively, of Fig; 2. F 5 is a view in side elevation of the grate and grate support, the burner, and the lower portion of the fire pot and shows a modified way of sup 'iorting a burner. Referring to the'drawii'igs, 2 doslirnatcs the upright cylindrical outer casing of 'the Specification of Eetters JE'atent. Patented Apr 22, llli ll lh Application filed au ust 21, nut. Serial No. cases.

furnace body provided at its upper end With seat-forming ring 3 to which the crown-like top 4: is removably secured by bolts 5, the crown being contracted upwardly at (l for connecting with a fine pipe. The lower end. of casing-2 is secured to and closed by the downwardly, flanged bottomiorming section 7, and secured thereto are legs 8.

The furnace lining is divided horizontally substantially midway its length as indicated at 9, below this division line the liner being formed in two vertical sections 10 and 11 which are jointed together at 12, Figs. 3, and 1-. The sections 10 and 11 are removably seated; on brackets 13 secured to the inner side of casing 2, and the lower portions of said liner sections are contracted downwardly to form the funnel-like ash chute 14; for directing the unconsumed products into a pan 1:) supported by bottom. .7 and removable through door 16. One side of" liner section 1.1 is formed with the outwardly flanged opening 17 to connect with frame 18 of the intermediate door 19. The upper at 29 around a stolting or charging opening" which is closed by door 3'0. When assembled, the diameter of sections 21 and 22 is preferably the same as the inwardly flanged upper extremity of the lower liner section,

and hence torms an upward continuation theroo'i". Bracketsv hold the liner sections at joint 9 in spaced relation -from outcr casing 2, and the same is true of ring 3 at the upper (ends of sections 2i. and 22, thereby. maintaining an uninterrupted air space 96 I irom the lower end of the casing, where air is ireely adnuttcd through the ventilated door 16, to the chimney connection, this space being open between crown and the crown-like upper portion 27 of the upper liner as well as in communication through openings 28 with the interior of said upper lining. With the furnace structure thus yentilated, the outer casing is maintained rela-.

tively cool, notwithstanding thehigh degree of heat attained Within the furnace.

For removing the lining, crown 4- is taken 5 oil? and section 21 lifted. out, whereupon. sec tion 22 may bemoved laterally to clear the stoking opening when. it also may be readily removed. And the same relative manipulation of '1ower'sections and 11 is had for 10 removing them after taking. out the upper sections.

The lower portions or liner sections 10 and 11 are formed with socket-like open-top seats 31 for receivin and supporting lugs 15 32 projecting from the horizontal ring-like frame By this means the frame is upwardly removable and may be readily put in place or takeii out asdesired. In the adaptation shown, said frame provides a supportfor the rocking grate and also sustains the gas burner,-and the latter in turn supports the fire pot. The circular grate fits within the ring like frame 38 and is formed in two semi circular sections 34 with each' section adapted to rotate on trunnions 35 which are removably seated in the upwardly open "nearing notches 36 in frame 33. Arms 37 projecting downwardly from the grate s'ections are removably entered in slots formed -in the grate-operating bar 38, this bar being slida'ble in openings formed in opposite sides of the hopper-like liner extension 14, said bar extending, to the'exherior of the frame and provided with the operating handle 89, whereby the grate may be oscillated for dumping as shown in dotted lines in Fig. 2. For limiting the movement of bar 38 its under side is notched at 40 for 00- 40 operating with bottom portion d1 of one of the guideways in part 14.

The burner 42 is preferably of one-piece ring-like form, with a fuel-admitting neck l6 extending. through side opening 44 in the 45 furnace body and to which a supply of mixed airand gas may be admitted by any suitable means. This ring-likemburner is seated on the upstanding lugs 45 of frame 33, and depending from the burner are complemental lugs at which may fit over lugs 45ers in F 2, or within said lugs as in Fig. 5, thus holding the burner in posi tion without, however, interfering with movement thereof vertically when inserting or removing it. The side opening closed by door 19 is of such size that this onepiece burher may pass therethrough, the door affording convenient means for manipulating the burner within the furnace so as may be necessary.

The the pot or basket is circular in crosssection and is arranged above and concentrically with the burner and in the adaptation shown issupported is formed. of a serigs of vertical segmental thereby. The pot sections at? which are jointed together at 48, Figs. 2 and 3. Th'ep'ot is contracted downwardy toward its open lower end to a diameter less than the interior of burner 42 so that the contents of the pot will pass downwardly to the grate without obstructing the burner. To accomplish this arrangement and at the same time provide for supporting the pot sections on the burner, the contracted lower end of each pot section is formed with the outwardly disposed ledge forming flange &9 having its outer extremity disposed downward slightly at 50 to overlap the annular flange 51 projecting from the upper side of burner 42, the flanges of the pot sections being curved complementary with said burner flange whereby the parts fit together with accuracy. Neck 4.3 of the burner when entered in body opening 44 determines the position of the burner, and for properly locating the pot sections,

f'the outer edge of each section flange $9 is notched at 52 to embrace the upstanding lug 53 on the burner, and these lugs are So located as to position one of the pot sections opposite the opening closed by door 19. By this means such location of the several pot sections is had as to make one of them readily accessible to the door so that all of the sections, including the last one inserted, may

be passed through the door, and also whereby one of the sections is readily accessible through the door when it is desired to remove the pot or basket fdr renewing the same or for any other purpose. With one section removed, the others are readily accessible and may be taken out One by one. Lug 54 on the outer side of each section provides a convenient hand-hold for manipulating the same, When in position, the up- 195 per extremities of the pot sections 47 are located immediately beneath the liner shoulder 20 so that there isno oil'set interruption between the upper portion of the lining and the fire pot or basket.

Flanges 49 at the lower ends of the pot sections combine toform a continuous ledge which overhangs and is of smaller diameter. than the burner and prevents the same from becoming'choked. The gas emitting ori- 1 1a fices at the inner face of the lourner are further protected .by the annular overhanging. burner flange 42.

The garbage, refuse or other fuel matter to be consumed is entered in the upper magazine-forming portion of the furnace through the charging or stoking door 30. This door and its associate parts comprise an embodiment of the invention of George F. Bib-1a,.which is described and claimed in his application filed September 8, 1915. Serial No. l9,419.- This door structure consists primarily of the outwardly and downwardly opening door 30 mounted at its lowor side to swing about a horizontal axis 55 on the door frame 56, the arrangement being such that the door is inclined when closed and hence held closed by gravity. Hinged to the inner side of the upper portion of the door at 57 is the chute-forming apron 58 which extends inwardly through frame 56 and when closed is in the steeply inclined position shown in Fig. Qwith its free portion projecting through liner section 22 for directing into the magazine any matter that might become lodged on the door when in open position. The vertical end portions 59 of the apron provide side walls for the chute-forming door, when the latter is in open position, and the projecting extremities 60 of walls 59 are adapted to en gage the top edge 61 of frame 56 for limiting the opening movement of the door, retaining the latter in the inwardly inclined chute or hopper-forming position.

The improved incinerator is designed primarily for household use in burnin garbage and other refuse, being adapted to e mounted in a kitchen or other convenient location for receiving garbage, etc., through charging door 30. The gas burner provides for developing such a high degree ofheat as to completely consume all vegetable and animal matter that may be deposited in the incinerator. The various novel features of the invention may be variously employed in furnace or stove structures without departing from the invention.

I claim:

1. The combination of a furnace body having the interior of its lower portion formed with upwardly opening seats, a frame entered in the body and having projecting lugs, adapted to engage the seats upon moving .the frame downwardly in the body, a grate reinovably supported by the frame, a gas burner above the grate and removably supported by said frame, and a fire pot above and removably supported by the gas burner.

2. Ina furnace of the character described, a cylindrical lower portion provided with inclined outlet walls, a frame supported within the lower portion, a grate removably supported by said frame, an annular burner above the grate and supported by said frame, and a fire pot above and removably supported by said burner.
